“It’s funny; I know they who they are, and then for them to turn around and know who I am, it’s very gratifying,” said Romo, who looked tiny compared to the men who were greeting him. “For them to see me as an equal professional athlete, it’s a thrill for me.”

Romo said he knows Alex Smith well, but admitted that his favorite 49er was tight end Vernon Davis. “He’s the one (autograph) I have to get,” Romo said.

Romo said he has been to about six 49ers game, but this is the first one he watched from the sidelines.

“All the game sounds you hear, it’s really awesome,” he said.

But while Romo was the starstruck one, the 49ers’ players were awestruck by one thing Romo had: a 2010 World Series ring.
